Struct gtk::CellRendererCombo

#[repr(transparent)]
pub struct CellRendererCombo { /* private fields */ }

CellRendererCombo renders text in a cell like CellRendererText from which it is derived. But while CellRendererText offers a simple entry to edit the text, CellRendererCombo offers a ComboBox widget to edit the text. The values to display in the combo box are taken from the tree model specified in the property::CellRendererCombo::model property.

The combo cell renderer takes care of adding a text cell renderer to the combo box and sets it to display the column specified by its property::CellRendererCombo::text-column property. Further properties of the combo box can be set in a handler for the signal::CellRenderer::editing-started signal.

The CellRendererCombo cell renderer was added in GTK+ 2.6.

Implements

CellRendererComboExt, CellRendererTextExt, CellRendererExt, glib::ObjectExt

Implementations

impl CellRendererCombo

pub const NONE: Option<&'static CellRendererCombo> = None

pub fn new() -> CellRendererCombo

Creates a new CellRendererCombo. Adjust how text is drawn using object properties. Object properties can be set globally (with [ObjectExt::set()][crate::glib::prelude::ObjectExt::set()]). Also, with TreeViewColumn, you can bind a property to a value in a TreeModel. For example, you can bind the “text” property on the cell renderer to a string value in the model, thus rendering a different string in each row of the TreeView.

Returns

the new cell renderer

pub fn builder() -> CellRendererComboBuilder

Creates a new builder-pattern struct instance to construct CellRendererCombo objects.

This method returns an instance of CellRendererComboBuilder which can be used to create CellRendererCombo objects.

Trait Implementations

Performs copy-assignment from source.

impl Debug for CellRendererCombo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CellRendererCombo

fn default() -> Self

Returns the “default value” for a type.

impl Display for CellRendererCombo

Formats the value using the given formatter.

impl Hash for CellRendererCombo

fn hash<H>(&self, state: &mut H)where
    H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl<T: CellRendererComboImpl> IsSubclassable<T> for CellRendererCombo

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for CellRendererCombo

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

impl ParentClassIs for CellRendererCombo

type Parent = CellRendererText

impl<OT: ObjectType> PartialEq<OT> for CellRendererCombo

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for CellRendererCombo

fn static_type() -> Type
